Hull Resistance

Looking for calculation methods to determine the hull resistance of a barge or similar vessel.

Any programs, spreadsheets, links or papers would be most useful.

Thanks

ChrisGibbs,

Looking for the information about Holtrop method or ( may be ) Series 60 method.

The limits for Holtrop method are:
3.9 < L/B < 15
2.1 < B/T < 4
0 < FnL < 0.45
0.55 < Cp < 0.85
Speed limit:
none < FnL < 0.45

The limits for Series 60 method are:
5.5 < L/B < 8.5
2.5 < B/T < 3.5
0.15 < FnL < 0.27
0.6 < Cp < 0.8
-2,48% < LCB < 3.51%
Speed limit:
0.282 < FnV < 0.677

Where:

L WL's length
B WL's beam
T Hull's draft
Cp Prismatic coefficient
LCB Longitudinal centre of buoyancy, measured from midships ( "+" is fore ).
FnL Froude number for wl's length
FnV Froude number for volume displacement.

 

Hi here is the reference of a sname technical paper


Model Resistance Data Sheets: 12 Barges
Authors: SNAME
Subject: Resistance, General, Model Testing, Barges
T&R No. D-8

make sure that if you use a regression method includes barges.
not any regression method will do for barges.

 

ChrisGibbs,

this is an approximate power prediction method by J. Holtrop & G.G.J. Mennen.

Dim.

 

barge resistance calculations

please if you have any calculation methods to determine the hull resistance of a barge,any programs, spreadsheets, links or papers.can you send to me
thank you

barge resistance

please if any one has data about bollard pull calculations to pull material barge please tell me on this mail (((( kamel_eng@hotmail.com ))))

thank you

 

Typos in Holtrop & Mennen's paper

Dim's copy of Holtrop & Mennen's paper should be treated with caution. I have found two typos, and am now satisfied with the results, having compared over a hundred different designs.

The errors on the first paper are for m1 - page 2 - should read -4.79323 (ie minus) and the final page, 5, c15 is -1.69... ie minus again.
